Once again in the sport of politics and the politics of sports, New York Times Columnist David Brooks and syndicated columnist Mark Shields talk with Correspondent Hari Sreenivasan. Topic 1: SuperPacs. Topic 2; Mark Shields and his uncanny ability to do long subtraction, on-the-fly. Topic 3; the Los Angeles Lakers fired their coach after a lousy start. There was even a Bieber reference.
